Researchers say an orangutan appeared to treat a wound with medicine from a tropical plant. It's the latest example of how some animals attempt to soothe their own ills with remedies found in the wild.
I’m not so convinced it’s from a common ancestor, tool use has been observed in a wide variety of animals ranging from birds to octopus, and that common ancestor is unlikely to have used tools. This seems more akin to that.
